It focuses on doing one thing well โ reliable secondary DNS โ instead of bundling it into a large managed-DNS suite. You get automatic zone sync with instant NOTIFY updates, genuine off-site redundancy on independent infrastructure, native hosting-panel integrations that most competitors don't offer, IPv4/IPv6, a REST API, and transparent pricing from a free tier up to unlimited zones โ no credit card to start.
SecondDNS is a dedicated off-site secondary (slave) DNS service. It automatically keeps a synchronized, authoritative copy of your zones via AXFR/IXFR zone transfers and answers DNS queries whenever your primary nameserver is unavailable. One-command plugins for cPanel/WHM, Plesk, DirectAdmin and CyberPanel register every new domain automatically, and a Personalized NS add-on lets you serve zones under your own branded nameservers. It starts free with 10 zones and scales to unlimited.
SecondDNS was built to make off-site secondary DNS simple and affordable for hosting providers and sysadmins โ turning what is usually a manual, per-zone chore into a one-command, automatically-synced service.
Hosting providers, web agencies, MSPs, and system administrators who run their own primary DNS โ often on cPanel/WHM, Plesk, DirectAdmin, or CyberPanel โ and need a dependable off-site secondary nameserver for redundancy and failover, from a single domain to thousands.
SecondDNS runs on battle-tested authoritative DNS servers using the standard AXFR/IXFR zone-transfer and NOTIFY protocols. It's delivered as a web application with a REST API and a dashboard, plus one-command integration plugins for the major hosting control panels.
